After playing around with the Emic 2 text to speech module, I decided to try having it read tweets. The gutenbird sketch from the Internet of Things Printer served as a good starting point as it already had the ability to parse the JSON feed from Twitter and output the content via a serial port.
It is possible to run scripts in Serial Speaker of 2 different kinds: Javascript scripts and Text scripts (Limited possible actions and SerialSpeaker proprietary format) To see which script is going to be executed, move the mouse over the start script button and a tooltip with the name of the script will appear. The default one is scripts. Text to Speech Maker V2.0.1 Serial number The serial number for Text is available This release was created for you, eager to use Text to Speech Maker V2.0.1 full and without limitations. Our intentions are not to harm Text software company but to give the possibility to those who can not pay for any piece of software out there. TextToSpeech.io is a Free online Text To Speech reader service. Accurate with natural voices, multilingual include English, French, Spanish, Chinese, Japanese.
For this project I used:
Connecting the Emic 2 to the Arduino is very straightforward, requiring only four wires:
Sublime Text Serial Key
While working with the Emic 2, I wrote a small wrapper class to handle the various commands. This is used at the beginning of the sketch to configure the voice parameters and later on to speak the text:
emic2TtsModule.init();
emic2TtsModule.setVolume(5);
emic2TtsModule.setWordsPerMinute(120);
emic2TtsModule.setVoice(BeautifulBetty);
…
emic2TtsModule.say(fromUser);
emic2TtsModule.say(F(' tweeted '));
emic2TtsModule.say(msgText);
The Social Chatter sketch diverges a bit from the original gutenbird sketch by explicitly expanding certain characters to words to control how the Emic vocalizes them. For example, the following code causes the # sign to be spoken as “hash” instead of “number sign”:
if (c '#') {
len = writeStringIfPossible(len, maxLen, dest, ' hash ');
}
Serial Key Text Speaker Review
During development, I noticed that having the Emic 2 read URLs was not particularly helpful. There is a simple state machine to detect links and replace them with the work “link” in the spoken output:
if (state STATE_NORMAL) {
if (c 'h') {
state = STATE_LINK_H;
…
}
} else if (state STATE_LINK_H) {
if (c 't') {
state = STATE_LINK_HT;
} else {
state = STATE_LINK_FALSE_POSITIVE;
}
…
}
